Executive brief
The Medeus theme for WordPress is vulnerable to a security flaw that allows unauthorized users to access sensitive files on the web server. By exploiting this vulnerability, an attacker could view configuration files containing database credentials or other private information, potentially leading to a full site takeover. This affects websites using version 1.14 or earlier of the theme.
Technical details
A Local File Inclusion (LFI) vulnerability exists in the ThemeREX Medeus theme for WordPress (versions <= 1.14) due to improper control of filenames in PHP include/require statements (CWE-98). An unauthenticated remote attacker can exploit this by sending specially crafted requests to include local files from the server. Successful exploitation can lead to the disclosure of sensitive information, such as the wp-config.php file, which may contain database credentials. While the CVSS vector indicates high complexity (AC:H), the impact on confidentiality, integrity, and availability is rated as high. As of the advisory date, no official patch has been released by the vendor.
